Besides being able to show the Current most active Players for this Month or Week, the Top stats are mostly interesting at the end of the Week or Month. So would it be possible to implement something like:
- [Top current month / week / day   (shows stats for this period since the last reset) ] Already implemente
- Top previous month / week / day (show stats for the previous timeperiod)
- Top previous 2 month / week / day (For example, i March would show Top users in January as its 2 months old)
- Top last 20 days / weeks / months  (shows total stats for period XX until Now)
